ObjectiveTo evaluate the clinical curative effect of modified Shaofu Zhuyutang on pelvic pain of endometriosis （EMT） with syndrome of cold congeal and blood stasis and the influence on neural angiogenesis. MethodA total of 110 cases were divided into a control group （54 cases） and an observation group （56 cases） by the random number table method. Patients in the control group took Aifu Nuangong pills with 6 g/time and 2 times/day. Patients in the observation group took modified Shaofu Zhuyutang with 1 dose/day. Course of treatment continued for 3 menstrual cycles. Dysmenorrhea， other symptoms and signs of pelvic pain， and the EMT health profile-5 （EHP-5） for patients with syndrome of cold congeal and blood stasis and EMT were scored before and after treatment. The levels of peripheral blood nerve growth factor （NGF）， substance P （SP）， calcitonin gene-related peptide （CGRP）， brain-derived neurotrophic factor （BDNF）， soluble Fms-like tyrosine kinase（sFlt-1）， vascular endothelial growth factor （VEGF）， matrix metalloproteinase-9 （MMP-9）， and insulin growth factor-1 （IGF-1） were detected before and after treatment. The levels of prostaglandin E2 （PGE2）， cyclooxygenase-2 （COX-2）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and other inflammatory factors were detected before and after treatment. The pain medication usage and recurrence were recorded. ResultThe scores of dysmenorrhea， symptoms of pelvic pain symptoms （non-menstrual pelvic pain， dyspareunia， anal falling pain， and defecation pain， etc.）， and signs of pelvic pain （pelvic tenderness and sacral ligament tender nodules） in the observation group were lower than those in the control group （P<0.01）. The disappearance rates of dysmenorrhea， pelvic tenderness， and sacral ligament tender nodules were 67.35% （33/49）， 73.33% （33/45）， and 77.27% （34/44） in the observation group， which were all higher than 45.83% （22/48）， 48.84% （21/43）， and 52.27% （23/44） in the control group. The difference was statistically significant （χ2=4.571， χ2=5.565， χ2=6.026， P<0.05）. The scores of EHP-5 and syndrome of cold congeal and blood stasis in the observation group were lower than those in the control group （P<0.01）. The levels of VEGF， MMP-9， IGF-1， NGF， SP， CGRP， and BDNF in the observation group were lower than those in the control group （P<0.01）， while the level of sFlt-1 was higher than that in the control group （P<0.01）. The levels of PGE2， COX-2， TNF-α， and IL-6 in the observation group were lower than those in the control group （P<0.01）. The total effective rate of the observation group was 92.45% （49/53）， which was higher than 76.00% （38/50） of the control group （χ2=5.307， P<0.05）. After 6 months of follow-up， the recurrence rate in the observation group was 30.61% （15/49）， which was lower than 52.63% （20/38） in the control group （χ2=4.315， P<0.05）. The average of taking ibuprofen sustained-release capsules in the control group was higher than that in the observation group per menstrual period （P<0.01）. ConclusionModified Shaofu Zhuyutang treated pelvic pain of EMT with syndrome of cold congeal and blood stasis by regulating the mechanism of neural angiogenesis， reducing pain， and promoting the disappearance of related pains， thus improving the quality of life. Shaofu Zhuyutang has a better clinical effect than Aifu Nuangong pills and has a low recurrence rate.
RÉSUMÉ
Objective:To establish risk stratifying criteria for acute rejection(AR)after kidney transplantation(KT)through analyzing the preoperative risk factors of KT recipients from deceased donor(DD).Methods:A retrospective study is conducted for 1 382 KT recipients of DD kidney at First Affiliated Hospital of Xi'an Jiaotong University from January 2015 to December 2020.According to the presence or absence of AR within 1 year post-KT, they are divided into two groups of acute rejection(group AR, 115 cases)and non-rejection(group non-AR, 1 267 cases). Clinical data of two groups are examined by univariate and multivariate analyses for determining the risk factors of AR and a scoring standard is established on the basis of regression coefficients.They are divided into three groups of low-risk(907 cases), middle-risk(450 cases)and high-risk(25 cases)according to the scoring results and the incidence of AR is compared among different scoring groups.Results:Univariate analysis indicates that donor age(AR, 793 cases; non-AR, 474 cases, P=0.033), age difference between recipients and donors≥25 years(AR, 63 cases; non-AR; 315 cases; P<0.001), recipient panel-reactive antibodies(PRA)plus donor-specific antibody(DSA)(+ )(AR, 96 cases; non-AR, 1 169 cases, P=0.002), donor kidney cold ischemic time≥12h(AR, 81 cases; non-AR, 1 064 cases, P<0.001), donor/recipient HLA mismatch≥3(AR, 70 cases; non-AR, 984 cases, P<0.001)and expanded criteria donor(ECD)(AR, 50 cases; non-AR, 790 cases, P<0.001)are high risk factors for AR(all P<0.05). Variables with statistical significance during univariate analysis are included for multivariate analysis.Five variables are finally determined, including age difference between recipients and donors≥25 years(β=0.61, P=0.006), PRA+ DSA(+ )(β=0.74, P=0.008), donor kidney cold ischemic time≥12 h(β=0.74, P<0.001), HLA mismatch(≥3)(β=0.81, P<0.001)and ECD(β=0.82, P<0.001). Score for each risk factor is calculated according to the relevant regression coefficient and scoring standard formulate on the basis of the above five risk factors with a total score of 36.With an overall incidence of AR at 8.32%(115/1 382), the incidence of AR is 4.3%, 14.7% and 40.0% in low/middle/high-risk group and the difference is statistically significant.It hints that immune risk stratification can effectively determine the risk of postoperative AR for KT recipients.The incidence of AR is significantly higher in middle/high-risk group than that in low-risk group ( P<0.001). Conclusions:For recipients with middle/high immune risk, intensity and dose of immunosuppressants should be appropriately boosted during preoperative induction and maintenance period.And the occurrences of AR and infection should be dynamically monitored.
RÉSUMÉ
Objective:To explore the clinical data of acute rejection in kidney transplant recipients of different ages with elderly donor kidneys.Methods:During January 2012 and June 2020, a retrospective review was conducted for clinical data of 298 recipients undergoing kidney transplantation from elderly donors aged ≥60 years after citizen's death.According to the age, recipients were divided into group A(age<30 yr, 59 cases), group B(30~39 yr, 125 cases), group C(40~49 yr, 83 cases)and group D(age≥50 yr, 31 cases). The incidence of acute rejection(AR)was analyzed.Also based upon age difference between donors and recipients, they were divided into two groups of(30~39 yr)and (40~49 yr)and the occurrence of AR was recorded.Results:The incidence of AR within 1 year post-transplantation in groups A, B, C, and D were 15.3%(9/59), 8.8%(11/125), 7.2%(6/83) and 3.2%(1/31)respectively.The incidence of AR in age difference≥25 yr group(12.5%)and age difference <25 yr group(5.3%) had significant difference( P<0.05). The proportion and absolute value of peripheral blood lymphocytes in each group at 1 week/month post-transplantation had significant difference( P<0.05). No significant difference was observed in serum level of creatinine(SCr), the incidence of pulmonary infection and urinary tract infection or the survival rate of recipients and transplanted kidneys in each group within 1 year post-transplantation among four groups( P>0.05). Conclusions:Elderly donor kidneys can obtain better transplant outcomes in kidney transplant recipients of different ages.As the age of recipients decreases, AR shows an upward trend.Clinicians should pay more attention to the prevention and treatment of AR in recipients with large age difference between donors and recipients.
